OKO Carburetor. Excellent choice for more throttle response and to maximize big bore kit potential.Sizes i carry 24mm,28mm, and 30mm Prices 60.00 plus shipping 6.95

Ruima race gears. This is a must if you want to go faster than the stock gear will let you go. I carry the 16*42 = 9.187:1 gearing. This is the best option for low end acceleration and top speed is 65+ mph. 50.00 plus 6.95 shipping

This is a must if you want more accleration and top speed. This works with the OKO carbs and Keihin carbs. Price is 50.00 plus 6.95 shipping

Keihin Pe 26mm carburetor. Keihin makes best quality carbs. Just remember this is just like factory but 10mm bigger. 85.00 plus 6.95 shipping

Want to add take off and improve your hill climbing ability. I carry 3 different clutch springs. 1000rpm is a small performance difference than stock. Will take off better but still is a smooth ride. 1500rpm is a big improvement over stock and will almost throw you off the back with the take off power. 2000rpm I only recommend for race applications. I have this spring on my 120cc stroker and it will throw me off the back if i am not careful.

Price is 10.95 plus 6.95 shipping

If you have worn and flat spots on your rollers this will kill the acceleration and top speed. I stock 3 different weights. 6 Grams, 8 Grams, 9 Grams. The 8 Grams or 9 grams work really well for most builds.                                                                                         Price 9.95 a set plus 6.95 shipping

This is a adjustable Ruima race shock. This replaces the terrible soft bouncy squishy shock. This shock is 300mm in full length but you can adjust it to suit your height and riding style. I would recommend if you want to run a breather on your oko carbs. The stock compresses so much it will hit the filter.   Price 75.00 plus 13.95 shipping
