Hey guys, I hope you can help me with your experiance... I rind a Rickter FR2 Evo with a 771cc 85mm bore SJ engine with B-pipe, 190psi compression and the usuall engine mods. My friend rode my ski a few weeks ago and blew the stock pump up totally, so I bought a used pump that according to the...

Hi guys, I was out running today, and I think I got something stuck in my cooling line... Result; wraped head, cylinder deck, and the front cylinder seized... I have some machining to do... However, I disassambled the top end and had a look at the piston. Right under the lower piston ring, in...

Hi, I've tried to search and I looked around on the web, but did'nt find a answer so I have to ask you guys... Does anybody know what pressure the Pro-tec cylinder head that is included in the "wake-up kit" gives on a bone stock engine, or what size it is on the domes? Of course the pressure...

Thank you Matt, very helpful! It's been a few months since I took it for a ride, and last time I had 1.5N&S and 95g spring and 72.5 pilots (cant remember the mains). Back then it was lean on low speed so I changed to a popoff on 35psi and to 75 pilots. And when took it for a test ride today...

Hi everyone, I've searched like a crazy person, but so far I did not find the answer I'm looking for. So please excuse me if Im asking on the wrong place (I'm a stupid Swede, I dont know better). =) I ride a 61x/62t with Watcon Sleeves #1820 84mm, with mild case porting, ADA head w/ 33cc...

Hello, I guess you will tell me to search, but I've tried, and did not find the info I was looking for... I'm thinking about boring my 61X-cylinder to 760, or at least something bigger than 701, because my sleeves and pistons are not in the best shape. My plan is to buy new sleeves and...

Yes, I know that I can use it. But I'm thinking about building my own nozzle, that's why I need the dimensions. The OEM Yamaha parts is Sweden is really expensive.

I'm thinking about building a C.A.T.S this winter, but I just wonder about how big the steering nozzle needs to be? Does anyone have the dimensions of the Waverider steering nozzle? The inner diameter between the pivot bolts and the inner diameter at the outlet? The lenght would also be...

Deleted my post. Don't want to upset someone. =) For you that already red my post; The plan was not to steal a design. Just to get a hint about how strong it needs to be. However, I will make the tryouts myself. I'm starting get good at landing bad with the ski. =) If it's possible, please...

Hi, This winter I have plans to leave Sweden for a week or two, to go riding at some other, warmer place in Europe. My thoughts is soutern Spain or Italy. I wonder if there is someone here that know any good freeride/surf riding spots in Europe? I appreciate all opinions! If i placed this...

Here comes the pictures. One is on the spacer itself, and the other in on the intake manifold and reeds. The question is if I can mount the reeds directly on the intake as in the picture (but ofcourse with the gasket in between). Because when I fill my crossover the spacer seems totally...

Tjena! Will try to upload a picture tomorrow. If you look from the intake and towards the reeds, the order is: intake manifold-gasket-spacer plate-gasket-reed cages. Seems that I have no use for the spacer if I fill the crossover. So my thinking goes: Intake manifold-gasket-reed cages. But a...

Hi, I've been trying to search for info about this, but it is not so easy when you are a stupid Swede, and dont know what everything is called... However, I took my 62T engine apart last week, planning to fill the crossover in the intake manifold, and make some port matching between the intake...

Sorry for going Off-topic, but how does the engine react on filling the crossover? Ofcouse there will be better flow in the manifold, but do you notice any difference when you ride it?
