maybe 2000-5000rpm. Not sure really, feels like it is popping at all rpms when Im not pushing the engine. If I accelerate it runs very well. Therefore I am thinking maybe a carb sync is needed?

A small update. I have now installed the UFO 4-2-2 exhaust. Shiiiiiiitttt THOSE are loud as f***!!! Even with the smaller endcaps. Tried the bike out for a week without adjusting anything. Crazy fun :P The super weird thing is that the consumption went from 24 mpg to 42 mpg! I have changed the...

My 85 has VIN JYA1GR00 2 FA000410. I think the "1GR" means its Canadian. Now it is imported to Norway. Just finished the restoration yesterday. All stock.

The spare carbs had 175 mains in them. In the the Dynojet stage 7 instruction manuel I found online thy say to install DJ165 mains if you have stock modified exhaust and DJ175 mains for aftermarked exhaust. Is the DJ175 the same as the 150 main jets you refer to?

Thats a great photo! Thanks. Ill by this shim kit if I end up with best performance between, for instance, between slot 3 or 4 from blunt end.

I think I will only change the main jets for now. Leave the needles as it has been. Bought the bike last year, beeing an 85 I bet someone have had an aftermarked exhaust on it before. So just change mains to 150 and test how the bike reacts to the UFO. Drive aroud for a day or so and then start...

Thank for your advises! I will try all this out and give you a feedback. I have been completely renovating the bike this winter, hopefulle be done and ready for first testride with the new exhaust early next week. Talk to you soon guys. You are the best.

Stock airbox, stock type filter. Altitude is at sea level. I do not have the K&N filters or the cranckase breather hose/vakuum hose and hope I dont need it. I also hope I dont have do drill the hole in the slides, get the stage 7 springs and the main air jet connector pipe. (I read the Dynojet...

Thank for all the good links and pictures! Really helped! Loved the main jet turorial. The new UFO exhaust is 4-2 with megaphone mufflers. I am intereseted in the picture of the needles. As you said I have Canadian needles with the slots, but I think mine looked more like the factory pro...

Thank you for your replies! so basically no power increse with UFO exhaust with stock carbs, and possibly loose some power midrange? Does anyone have any pictures of what is the main jet? I looked today, screwed out what I thought was the main to check for the "152" but just some strange...

Hello! As the title says I am wondering if I have to install a stage 7 kit when replacing my exhaust with a full UFO exhaust with the megaphone cans. It is a 1985 full power Canadian version. I pulls like crazy.. I think the carbs are all stock (how can I find out btw? measure the jets?)...
