Hi guys,
Quick update - I took the bike another ride yesterday after upgrading the sprockets (from 15/41 to 17/37) & it is heaps better - 1st gear is nice. I wouldn't even mind going with a 35 rear. The clearance is tight between the chain over the top of the front sprocket & the engine case - as long as i maintain correct chain tension it will be fine - here is a pic (5mm clearance at most i'd say):
I also spoke to Casey from DHZ - what a champion & really accommodating. I asked him about tuning & he said as long as it is not bogging or hesitating, just leave it as is good advice imo.
When I rode it yesterday, I stalled it on a steep hill & it took quite a few kicks to start it again - I asked Casey & he said that the fuel evaporates when the engine is hot so I could try start it next time with the choke on OR he thinks that I should adjust the air mixture to 1/2 turn out from tight and increase the idle & that will deliver more fuel when restarting. I'll try it as I'm not sure if it will hold a clean idle on this setting.
When I adjusted it to 2 turns (current setting), the revs did not noticeably change once I got past 1/2 turn from memory - I did trial it & screwed it in all the way & it bogged down wanting to stall but like I said, once I get past 1/2 turn the idling is clean & seems to peak there.
Lastly, these Braaap stickers tend to peel off on some of the tips (more around the rear where there is exhaust heat) - is this normal as I keep pressing down the edges where it lifts? I was told to use contact cleaner, however, I used metho which is great for cleaning & non oily.
