Ace - The current carb is Mikuni VM34mm. I just replaced the manifold from nfield. Will that one fit?
OK, got the carb in as well as the Goldie exhaust. First impressions -- it idles better (had a vm34 in before) and sounds great. It was a little hard to start though and on my little ride around the block it seemed to be lacking in power and struggled in high rpms. I had a hard time finding a good jetting start point on the board but went with a P6 needle, 30 pilot and a 190 main. Needle is in the original position. I'm at sea level and am using an ace canister. Engine is stock otherwise...Does this jetting sound OK for a start point? I'm willing to do plug chops just would like to have the correct jets around before I start. Any suggestions? Thanks.
I got the 32mm flatslide installed. If anyone gets one be sure you get a 'right' one. The choke on mine is on the left, not right side. The gas inlet in on the right, not left side. This is the opposite of the older round slide. I don't know if there's an option of different sides, but if you can get a mirror layout carb, get that one! Can't do any riding yet. Gotta get a new duckbill. and get my header bracket welded. Working on it!Bill
So I got the p8 and finally got some time to put it in this morning and no, definitely not going to run on a p8. Good thing I've got some other jets so I put in a p4 and yes! That's the right direction. It's still a little sluggish so in goes a p2 and now things are seeming great. It's got a 180 main in and I'm wondering if I could go leaner there as well. Got the needle in the mid position but may try leaning that out when I get a chance cause it still seems a little off. Basically, it seems like I'm going to have a jetting very close to, if not the same, as Chucks fireball. I still want to do plug chops but I'm going to have to find the time to get over to Jersey where I can find the space to do them......I have a left choke too. Sounds like they are all this way. It's annoying but on the plus side I'm hoping it will discourage me from tinkering with the idle and air screws. I seem to be always messin with them.....
Thanks Ace! I dinked around with it again today. Put a 195 main in and took her out for a longer ride just to try and feel where I'm at. It idles well, pulls away nicely but sputters and loses power around 1/2 to 3/4 throttle. When I got back the head seemed hotter than usual leading me to think I'm running lean. Unfortunately, I do not have the richer P8 and raising the needle didn't help (and boy does that spring on the flatside drive me nuts!).I have a boyer mark4 and haven't touched it since I bought the bike. It has always run well, started in the first few kicks, never pings so I figured the timing was set and best left alone. I'm assuming that changing the carb and exhaust shouldn't effect the timing right? And frankly, I do not even know how to adjust the Boyer -- same as points? Move the plate counter clockwise to advance?It's going to be a pain to find a place to do plug chops in New York City so I'd like to have all my ducks in a row before I head out to wherever to do this. I'd like to do it only once. Anyone familiar with New York have any ideas where I do these chops without putting my life in danger?
IT RUNS!!I got the flat slide installed and fixed the duckbill. I went for a start. Put the choke on. Not much happened. I pulled the plug and it was wet. I kicked it over to blow out the gas. Turned off the choke, and ONE KICK, pow, it started. I blew out some smoke. I believe my broken header bracket might also be a hole! (I'll get it fixed this week.) In the driveway I adjusted the air and idle. I got geared up and went out to pick up my carry out dinner. The engine feels better. I'm getting a bit of pops on deceleration, maybe the pipe. The clear duckbill tubing isn't filling up with oil, finally! Lots of improvements all at once. Even during warm up, looking at the exhaust, I'm rich all over. Right off idle, I'm getting a chuff, a puff of exhaust smoke, [rich]. When I would blip the throttle, more puff. I'm running a 27.5 pilot, a 190 main, P6 needle jet and the stock needle [5FP17?]. But, overall the motor is noticeably improved. The power band is positive across the whole rev range. The old big 34mm was happiest with a handfull of throttle. This one feels good all over. Would a leaner needle give a leaner overall effect?!Cheers,Bill
