Lack of snappy throttle can just mean the carb needs a nice ultrasonic clean once in a while, it really pays off and at least you can find out if the previous did anything suspicious like putting the wrong jets inside which makes a bike a little too rich when its hot. Fortunately, this site has various carb tutorials for carb tune ups. But before you or anyone attempts to open the carbs, please get fresh screws from the shop and discard the old ones. Never reuse old carb screws. Also as it s JAPAN carb, use a Jap screwdriver called “JIS” screwdriver, cause UK drivers will instantly round off the heads. Incase you or your mechanic not aware. Plugs, are always an easy replacement, stock ones work okay, but age or mileage (whichever is first) will make them wane, new ones go a long way. If you look under the bike and you have silver colored pipes, then you have stainless pipes from Black Widow UK , or Scorpion , or MTC (rare) or MotoUnion (too rare, out of business) or even TK ones , they will discolour a bit with heat. It is normal. Hope you enjoying the bike, post the in Tech section if anything comes up. If not, share a picture of her here;
Hi Marcel,
Thank you so much for the info as i wasn’t aware japs had different philips heads to us so i shall have a look for the correct driver.
The exhaust is the standard black one with the standard can on it. I would like a SS system on it just to let the engine breath a bit easier and to unleash that nice V twin sound.
Will get a pic posted of the bike asap.
Thanks,
John.
