I'm not sure who cut them I bought them off a member o the board. As far As I can tell reading the numbers done Volume is 20cc squish angle is 13 and 115 for long rod. Stock timing stock carbs 330 mains. I'll have to use another gauge tonight

Stock timing

They were 23 mm I believe but then cut for 4mm dome has some engraving 20 13 115

At 155 psi I didn't think I'd need higher octane. I'm about 1000 above sea level

Can anyone tell me why my Spark plugs are Coming loose? It's a cool head with 20cc 4 mill domes running 94 octane

390 is huge what motor do you have?? I got a 4mm dune ported and I'm at 340 mains 25 pilots

I can't for the life of me bleed these brakes. I just changed a caliper on the front and I tried for about 5 hours to bleed them. Pumped them and opened bleeder and sometimes fluid came out slowly and other times air. Reservoir never dropped. Hooked up a line to the bleeder then to the a bottle with fluid attached to a chain above the quad. Played around with the lever while the bleeder was Open like a YouTube video showed for a good 2 hours. This will not Build pressure for the life of me. I ha. Good solid lever squeeze before all this. Help me

Leave pilot stock 25 and try 290 mains stock needle middle clip

Got the crank off a member new but opened in box. Was wondering of these are supposed to be welded from factory? Couldn't see any welds on the pin. Can I tell which crank it is by the number on the rod? As far as I can tell the rod does look longer. Thanks

So the green part faces inside clutch cover?

Need to know what direction to put both crank seals ASAP

Can't do shit Anyways who wants his number

I'm pretty sure I sent as gift I'll log On see what I can do
