Hi everyone! I need some help on my beloved 2007 VTR250, she is having some issues with her idling, and stalls occasionally. First some background on the bike: I bought the bike in April, with just over 30ks on it. The previous owner told me that it haven't been used much the last 12 months, just occasional rides. When I picked it up, it was idling poorly, and he told me it was because it was low on gas. After filling her up, she still wasn't idling perfectly though. Now I have put about 2ks on the bike, and there is no problems with the engine; except the poor idling and stalling. No flat spots or bad torque. The bike is 100% stock, no slip-ons or nothing. As for servicing, she has been regulalry serviced, although the last service I have paperwork on is at 18ks. The previous owner stated that she was serviced at 25Ks as well, but have no paperwork to show for it, so I am guessing it havent been. The problem: She idles poorly, and stalls occasionaly, usually when I let go of the throttle and she has to return to idle. This is especially a big issue when I'm riding in slow traffinc or in the city, and engaging/disengaging the clutch alot. The bike will stall and start up at once, but after 4-5 stalls the battery is out of juice and I have to jump-start her by running into gear... Which is far from ideal, and makes stopping on steep hills and riding in the city a nerve-wrecking nightmare. I can manage to recreate the problem when it is idling: see the video below, and you can clearly hear that she is struggling with her idling. She also idles around 1k - with the service manual stating that it should idle at 1.3k +/- 100. SEE VIDEO HERE What I have tried: My mechanical skill and insight is limited, but I have picked up a couple of things I have learnt during my years... - Oil change Should the last service have been at 18Ks, a oil and filter change was way over due... So, I changed both the filter, replaced the o-rings, and topped her up with the genuine Honda-oil. - Methylated spirits in petrol I learnt about that trick here on this very forum, if there were to be some water in the carbs or fuel this should have taken care of that... I added about 20 mLs, one cap, but there was no difference. - Checked Air Filter Nervous and poorly equipped with a spanner-set from the reject shio and a IKEA-toolkit, I took off the petrol tank and checked the air filter - which supposedly was to be changed at around 20K-service. I have no experience with these filters, it is dirty but not clogged: see picture here. I also wanted to check the fuel filter, but it turned out the VTR250 does not have one. My plan was checking the spark plugs as well, but with the limited amout of tools I have I didn't stand a chance of getting them out. I am out of ideas - and this issue is really annoying me. As a student with limited funds and a will to do things myself, I really want to figure this out and fix it without dropping her off to a pricey mechanic. I appreciate any thoughts and ideas! Thanks!
