ran another tank on sat, 35+ degrees. I think the revs have dropped off slightly but this is prolly me just being paranoid. I ran with Greg and he assured me the engine is fine, still looking and sounding great, so i wont stip the engine down and keep running it.
something seized up in the front end, initially thought it was a bearing. it was time for a complete strip down again anyway so i spent 1.5 hours in the garage last night and took it down to a chassis. found the problem, the two belt pulley/guides have two bearings on each, one on either end, both of them have melted the plastic pulley/guides again, this happend on my last tear down which was only 15 or so tanks or so, pretty dissapointing.
from what I can tell the bearing is getting so hot its melting the pulleys and then seizing up the pulley from turning, so instead of the pulley turning with the belt the belt just slides over the over the pulley causing more friction and heat!
ive ordered two new pulleys (only $20 for both) and some rubber sided bearings, hope these generate less heat, there's no alloy pulleys which would have fixed the problem but hoping that the better bearings do the trick. Ill get some pics up tonight of the failed pulleys to show what I mean.
The rubber sided bearings that I got for the belt tensioner is holding up great, still super smooth and quite.
Also bought a outlaw filter set up and v stack from a member here so going to try that out when I get it back together, haven't had the filter off yet to see how the grease mod worked out but was only racing on grass so not much point i suppose.
