There are two Top Dead Centers BTW, and only one TDC is useful for setting the valves, the one that has both rocker arms loose. AKA the compression stroke. On some engines it is hard to get to that one, because as you rotate the motor at the flywheel, it will lurch forward on its own and pass the TDC you want. The solution is to not use a ratchet wrench, instead use a breaker bar in order to have control of the engine spinning. You can also use a normal box wrench of the right size as a breaker bar, if you have the adapters below to insert into your socket. Any hardware store should have them. A lot cheaper than a breaker bar, if you don't have one of those. Here is the exact same product, far cheaper at HF. https://www.harborfreight.com/3-piec...aps-67011.html https://www.amazon.com/Square-Drive-...ps%2C99&sr=8-2

Exactly 1600rpm like it says it should in the little book that came with it. It’s killing me. I have to get into those valves

I'm pretty sure he has the OHC. Only remove the two caps.

So I tried adjusting the valves and hanged the spark plug and it was no use for the heat coming from that engine and header. I think the techs I was dealing with at the beginning have not had much experience with this bike or with this kind of problem. Venom has started making this right and it turns out this bike has more problems than should be the norm. They have been really helpful now that they have seen more of what is happening with the bike and that its not just the normal heat coming off the engine. They really came through now and are helping me get this all straightened out. Big thanks to JerryHark250, helping me get some more help and advice. Thanks to everyone who has helped and given advice. Looks like it is time for a different bike.

Dunno about that Hark guy. Sounds sketchy. OP, recommend you do the exact opposite of whatever he suggests.

On post #21 it appears that you are trying to adjust the valves with the engine hot. As far as I know these valves are to be adjusted with the engine cold.

Yeah OP, just in case you don't know, you should let the motor sit overnight before adjusting the valves.
