Hello everyone! This is my first post.
I have started racing my WR 500 at the local sand drag track here in Arizona.
I am not familiar with engine performance modifications to 2 stroke engines, I mechanic on Top Fuel Bikes and Funny Cars.
I would like to do some work on the WR engine, but don't know where to start.
The engine is stock, 487cc, and has an FMF pipe and silencer, Boyseen 2 stage reeds, and I removed the stock air box and installed a Uni round air filter.
My best times with the bike, paddle tire and strut, is 5.39 @ 60 mph. The track is 300' and altitude is around 1,500'. I have just installed a 10" over swingarm and lowered the chassis. I will run the bike as is for the next few months, we are starting our winter series. But, I want to start getting advice on what to do engine performance wise. I hope to start engine mods around June/July.
I would like to move up to the MP1 class, which is 4.49 and quicker. I now run the MP2 class, 4.50 and slower.
Thanks for any help!
Patrick
