Hello first post on here love the forum lots of good info! I brought my 1990 VN750 out of storage and I'm trying to get it back running, bike would hardly idle only with choke on so I removed the carbs to clean after taken them apart I found that the idle jet is clogged and also a #38 and full throttle jet is a #135. I traded for this bike and it was already setup like this already. When i got it it would back fire/popping noise during deceleration around 50& up and would not go above 80 at this speed it started to back fire on rear cylinder regardless so I put in the back of shop walked away 2014. 2022 New saga begins. I know I need new jets due to exhaust ,question is which ones I live and ride 90% of time at 121' to 5' above sea level but will be riding at 800' to 1000' once a year. There is a lot maintenance that has to be done and that's Kool keeps me busy at night like front fork seal's brake calipers rebuilds etc. while I have carbs out was thinking of doing a ear shave job also just wasn't sure about getting caught out in the rain while riding with exposed air filters, we have summer storms that pop up from no where here during the summer.
