06-15

only the exhaust cam works 06-08
But most of the gain is from the intake cam
She made 49HP

Nice! All dynos read different so numbers a whatever. The end result of it running better is what matters. You really need some cams now.

She ran great at the dunes. Beat Hondas and Yamahas with similar mods. Launches good in either 1st or 2nd. Super light wheel set up too with my new skat traks all around. Spent a lot of money overall but it was well worth it. 450cc cp carillo piston on vp110 and lone star suspension dyno tuned by Garrett @ fuel customs motor built by ArrancaHuevos motorsports out of the Central coast in CALI

what did it cost if you don't mind me asking?
Over $6K in parts full engine rebuild , suspension, wheels and tires. Worth every penny . I bought the bike in 2018 for $3,200. I’ll see if I can upload a spreadsheet of the costs later.
