Surfriding tbm flywheel doesnt fit keyway or crank taper?

[DK-Freestyle]

Something is fishy with the TBM's...Nearly every flywheel I have seen has had some sort of problem with it. At the very minimum, the flywheel has somehow destroyed the bendix and then eaten bits of it. I've probably seen that one alone about 4 times. I've never seen a TBM flywheel that has been used for a considerable amount of time and come out looking like it did from the box.

I'm not 100% on that statement. I ran a TBM flywheel for 3 years straight, and the only marks on it were greasy finger prints. Only reason I'm not using one now is because I switched to total loss.

dk,I know guys that have ridden 3 yrs straight on a ski with maybe 20 gallons total,lol how many have you put through your ski.surf guys usually ride ALOT. thats reassuring though that someone has had good luck with the tbm fw. If he really has over 1000 out there,maybe its just the few that have messed up keyways that are causing all the issues

wow looks like metal dust everywhere.....????? ya no TBM products i my future for sure. This thread makes alot of ppl want to stick with a stock lightened fly wheel fo sho

 

[ATS_Aaron]

1000 of them sold. Haha. I doubt it. Plus a 1% defect ratio..between Wattage and I we know of 5 bad ones, plus your sticky one makes 6. That means we got 60% of the defects. Total B.S.

I couldn't agree more....

Yes, I did the testing with the Epic and TBM, and I can assure you that it worked perfectly. In saying that, the TBM flywheel that was sent to me for testing already had scuff marks all over the inner circumference of the flywheel from the teeth of the bendix that were floating around.

Ring TBM and see how helpful they are when you mention the Epic ignition...

So, there probably is a few out there that are just fine, but the overwhelming response seems to be that people won't use them because they are plain unreliable. I could go on to name around 15 guys here in Australia that have had problems and refuse to use the TBM ever again. Why do I only mention this now? Well, I'm not one to stir , but reading some of the info that has been posted (just like Aaron) makes me a little angry. I've been trying to find a decent ignition/flywheel combo for the last 7 years, and have been given the run around from plenty of the big names.

I believe the tbms work with the advents with a serial number on the advent starting around 7000+. The earlier advents had the issues with back fireing and rough starts. Anything below the 7000s and greg at advent won't even reprogram em. Greg also tolm me he worked with tbm to make em work together.

Yeah, I know what you mean. But I've put easily 200+ gallons through the motor with that flywheel. Our shop is a quick walking distance from the water, so we ride all the time. My old motor with the flywheel is now in the Demo BOB ski, and it's still being ridden a lot. But it could be a new bad batch that's being sent out.

wattage,this isnt stiring ,this is posting up the truth on what works and what doesnt,Id of never spent the $ on the one I have if I had known all the issues everyone else had with them. all I read everywhere was it was great. The advent ign is a total joke as well.Im gonna be upset if I buy a epic ign and then find out later on their were problems with it as well and no one said anything about it.Thats the whole point of a forum like this,no use kissing the manufactures ass on crap products,especially if they arent looking out for you and at least giving you a new one,thats how greg at advent kept selling them so long,he was replacing them constantly so guys kept it to themselves I guess. Doesnt make it any less a POS

 

[Watty]

wattage,this isnt stiring ,

Not saying it is....what I'm saying is that this the reason I never rerally commented, because I know how most of these threads end up. I'm probably the most disgruntled customer out there when it comes to not getting what I paid for, but I'm not one to really put it out there, UNLESS I see an excuse getting the way of the truth.

It's funny how different the stories are. I am running 2 TBM's on 2 different skis now and have run both with the EPIC with zero issues. I had tried an Advent but it would not work with the TBM as advertised.

I'm glad ive had better luck but i will say that should anything go bad, i will be going back to a stock fw and not look back. Yes there are gains to running the tbm bit definately not worth the $$ or the risk. I used tp reccomend the tbm to everyone but have backed off on that as well even before this thread.

 

[cambo au]

i am really glad i was given a link to this thread as i to have had a gut full of TBMs stuff
i bought one of the first batch that was made by tim at the world finals when they where first released took it home used it and was more than happy with the gain and i sent tim a email saying that this was one of the best mods i had done to my ski besides a B pipe which he used the statement i made to put on his website afetr maybe a month i had a bendix let go other than some wear marks on the inside of the flywheel i could see no reason why it should not work but it was stuffed it just would not fire so i rang and emailed tim who said send it back he had his machinist take a look at it and they could not tell me why it was not working either so i bit the bullet and bought number two he was kind enough to sell me this one at distributor cost but then he charged me $100 for the machining on the stuffed one so i really only got it for dealer cost this one also broke but this time it cracked through the key way i didnt even bother trying to contact tim as i knew the answer so now i am running a ATP Flame i can say in all honestey that i torqued it up to the exact torque setting when it was removed i would never buy another one and i advise everyone not to also with just the 10-15 guys i ride with we have had at least 5 break out of about 10. unfortunatly with it being the lightest one on the market he will keep on selling them
i wasnt worried about the price when i bought them but they overpriced considering that you need to buy one a year
i really hope someone tells Tim about this thread and he monitors his quality control better and future customers dont have the same experience

Weird... I have an older one. Got it a few years ago. Even got it slightly used. Haven't had any issues with it at all. I go through about 5 gallons of oil a season so its not like I don't ride the thing.

This is where TBM's story gets fishy. Yesterday they told MasterBlaster that none of them were compatible. Two years ago they told me no problem and specifically made to be compatible. I spent about $2500 between TBM's junk and the necessary repairs from the damaged caused by their junk.

 

[Matt_E]

I contacted Tim directly a couple of years ago to ask about the Advent. He told me that they were working on a version of the flywheel that would be compatible. Square magnets, I believe. In retrospect, I am glad I did not waste my money and went with the ATP Flame TL instead.

 

[OCD Solutions]

My advent did not work with either of my 2nd gen TBM flywheels. I even have an email from Advent saying it will and that the serial number is "one of the good ones".

Hopefully ATP will have a charging flywheel available soon and we can all move on.

 

[masterblaster]

in2...I dont think after this I would waste my time with a charging flywheel for the stock stator.By the time you buy a epic and charging fw,you may as well just get a flame or msd tl. I would also be interested in hearing how well either you skis do with a stock fw,The lightened stockers are a waste imho also,they only lose a few ounces,you are gonna have to lose at least 16oz to feel a diff at all. What would your ski run like with the tbm and advent?

 

[Matt_E]

Friend of mine runs a TBM with advent

 

[masterblaster]

as mentioned above,I have a friend who runs advent and tbm as well,but it runs like crap and so far has not been able to be tuned out,he is switching to a stock fw soon,Ill let yall know what it does afterwards

Matt...so how does that ski run?

It seems strange so many people have blown bendix issues running a tbm also. The ring gear is much more thin than most aftermarket fw.hence the slight weight diff in the tbm being lighter ,ever see how beefy the ring gear is on a rab or jetinetics in comparison? all it takes is one tooth to break,and get into the bendix or between the fw and stator and its toast,alot of people are reporting these issues with the tbm,rad and jetinetics both made changes to their ring gears before they arrived at their final revision of them that lasted,and even then the rad would occasionally spin the ring gear unless it was sent back and pinned.

 

[OCD Solutions]

Ask ScottS how his ski runs with the EPIC and stock fw. He's the reason i wouldnt spend the money for another. His first gen tbm wouldnt run the epic so has been running with a stock fw and the difference is negligable.

MB, you are correct, if anything happens to either or my tbm's i will be all over a Flame without hesitation and the Epic goes in the wifes ski.

 

[skinnyman]

I was one the first ones to use tbm flywheel It didnt work with Advent Waited a month or so Tim sent the sq magnet version I worked well with advent
Lost a bendex scared up the FW pretty good and bent the ring around the face
I beat the crap out of it with a small hammer and installed it.Im still running it today 3 yrs and counting
Sounds like I got lucky
The truth of the matter is I didnt get good support from TBM on the advent issue round mag vs sq
Paid shipping 3 times and waited around for it
Im not running advent anymore do to advent issues
Im still running TBM untill it gives up then its ATP Flame for me
