Running hot after jetting changes

2 posts in this topic

I have gone to the following jetting;

35pj

50pas

emm-3

155mj

160maj

Running yz timing, air box lid removed, wb-e series pipe with 7 disk. Less than 1000'

Engine temp seems to be running hotter than before.

Does not seem to run lean other than the engine heat.

My question is: Has anyone else had any problems running hot on the leaner jetting settings?

Thanks...

If it started running hotter after changing jets its probably running lean

Running lean melts pistons, rings and valves

Do a search on jetting you should find someone in your neighborhood and see what jets they are running
