The NFS kids where in Kalmar last year and they where pretty good but didn't win ;) It's sad that there is different rules in most countries, I have raced in Denmark and have to use another engine there. If you want to come over most drivers uses a zongshen 155 engine with TB head and that...

Hehe, are you coming to the nordic cahmpion in Skaerbaek Denmark 20-22 May? You are also welcome over for the next race in Borlänge Sweden the 5-6 June. Class rules in Sweden max 169cc 4stroke and max 15hp on the wheel. I bet you can beat me, I am one of the slowest, but we have some pretty...

First race, was wet race and I had no wet tiers so filmed from the side YouTube - MVI_7158.AVI second race from my helmet YouTube - Västerås hjälm kamera.wmv

Hi, Was att my local rider store and found to me an interesting carb, a Walbro WVF 28mm and bought it. The carb usually sits on Gilera Runner 125-200cc 4 stroke engine. Dose any one here have any experience with this carb? I am going to try the carb on a 166cc zongshen with TB head, what...

I have had the same problem, the rubber was hopping out, so I fixed the rubber with an extra screw, then it started to leak oil from the cylinder gasket, so I put some extra filling around the gasket and then I blow up both the blocks. I have teared the engine apart but still don't know what...

Oki, I have always thought that high rpm is more critical for these dirtbike engines, but with a bigger cam and high compression it can be different. That ping sound is really not what you want. Had a new engine that made that ping sound every time I opened the throttle, but I was lucky to get...

Denmark. Almost every country in Europe have some different rules. In some country's I know that Japanese engine are forbidden. Well not much to about the regulations.

Long tread, but some good info there :) I think I will get a tool to measure the actual comp for MY engine, small differences on just how hard you have put the bolts on and so on will make it very hard to get the calculation correct. Start to first build up the comp in the engine seems like the...

In the product manual it says that you have 13.8:1 compression ratio with the high compression piston (page 23 if you haven't seen it, witch I doubt http://daytona-global.com/products/pdf/84346.pdf ), is that totally wrong? I haven't measured it my self but if thats so wrong it would be...

I already have the high comp piston in the engine, the racecam is still on the shelf but will be installed soon. Going to leave the head to a pro for porting work, so hopefully I will have 16-17 hp on the wheel. Thanks for the input

Alright, so in the end carb size is what really matters? I still have my keihin PE 26mm, but putting that on means I loose a little bit more than one horsepower on the top, sad to hear.

Hi, Since almost all pitbike forums seems to have some kind of hate towards the PWK style carb and this forum actually seams to have some people that have got the PWK run well I post up my issue hear. I am racing the motard style and competing in a class with the following limitations: max 150...
