well bit of an update on this one .... the walbro is great, methanol however seems not so great
after various attempts to get the bike to start i was continually getting lean out and it would stall shortly after starting .... i eventually decided to pull the carby apart fearing i had something blocking a jet or something .... turns out there was alot of gummy stuff in the carby and was blocking the gause filter thing, so i gave it a good clean out and put it all back together and its now running fine on petrol ....
i was enjoying using methanol but i guess over time its just not worth it ... im not sure if its just from sitting for a few weeks since i last rode it or just from a slow build up over the last few months of methanol use.
