| Lack of petrol flowing Out at Oulton yesterday and a previous afliction reared its head. After a few laps (5/6) the old girl ran out of puff at turn 2. As they had limited marshalls I tried to limp home and after knickerbrok she suddenly had a second wind! Second session and the same happened again  Now I had an issue at Snetterton last year thta felt like a fuel issue, I had the carbs stripped and rebuilt and set up for the new pipes in time for Cadwell and it were fine at the end of last year. Now the Mrs did drain my tank to the bottom for the petrol! Got the bike out today, started to drain the tank and what started as a good flow turned into a trickle. Then after unscrewing the petrol cap (replacement race item) the flow was restored! I suspect either 1. there is rubbish in the float bowl again or 2. The flow is not enough Its a monster tank with the vacuum pump (which I thought we bypassed but I may be wrong). How does the air get back in the tank to replace the fuel going out of the tank so we dont get a vacuum? There seems to be no hole in the race fuel cap although there looks like a mini ball bearing (0.5 to 1mmm in size). The SS tanks used to have a pipe on the top with a valve? What does the monster get? Am I looking at the right thing or am I going to have to pull the carbs kff to look at the float bowl. Tried blowing through the fuel cap to see how air could get in and it did not seem to work. Very puzzled bloke  |
