    Hi everyone, I'm new to this site and not all that sure I know how to get around! My little brother has intorduced me to the site and says he's had some great advice and made a few friends along the way.

    My ride's a 2008 Vstar 1100 classic. Bought it recently from an interstate guy that had it for about 8 weeks and only put 1000klms on the clock. It arrived at my door in absolute brand new condition just like the day it was driven out of the showroom with a price tag of about $5000 less than market. So I got a great deal!

    Now I have a couple of niggly things I need some advice on. I also want to know if anyone else has had similar issues and if so how you resolved them.

    My 1100 vstar classic is all stock standard - no mods mechanically.

    1. When the bike is warmed up, occassionally I get a very bad flat spot in the throttle response, the bike makes a sound ...it "pops" something of a backfire, and I feel the "pop" vibrate like backpressure into the carbie/airfilter housing. It tends to do it when I'm kicking down the gears and go to flick the throttle to bring the revs up to the next gear during kickdown. Someone has suggested maybe it's the carbies are running lean but not sure. It just seems to intermittently have a "dead spot" when I try to power the throttle and I get the backfire "pop" sound and there's absolutely no response.

    2. The drive train has developed a secondary "clunk" sound when I engage the clutch on changing gears up (first to second, second to third etc). the vstars I well known for the initial clunk when you change gears, but this is a secondary clunk when I release the clutch to engage. The local yamaha dealer says its backlash (play in the gears/pinion or whatever else in the drivetrain). I'm concerned there's something not quite right in the gearbox..maybe in the clutch basket setup. It doesn't seem to have the secondary sound on engaging the clutch when it's cold, only when things warm up.

    Any info is very much appreciated and I hope to hear back from a few people! Thanks!

    And, one last thing...great site!

    welcome to ya from down here in wollongong area

    1 i had a bad throttle poppin issue not long ago
    had a carb sync and still had probs till we found a pipe kinked that goes from top of carbs into a box under ya tank
    had the mech pullin his hair till he found it
    maybe have a look at that cause if someone has removed the tank and not put it back properly

    2 maybe try a oil change and try that
    but with 1000kms on it should be under warranty so get it looked at and a service is probly due any way

    Hi again Mick,
    It's still under warranty and at the moment has just over 2000klms. It's had the first service and as youve suggested, I'm considering doing a fresh oil change myself on the motor/box as well as the diff cos I don't put a lot of faith in the Yamaha dealer that did the 1000klm service. I'm nor going to worry about the filter because of the difficulty with having to pull the pipes off to get to the filter housing..and Im pretty sure they did the filter at 1000.

    the carbie issue I believe is probably an adjustment issue and the dealer just fobbed me off last time I went to him a few days ago. Short of going to a specialist and havingthem do a proper adjustment and maybe even a dyno tune, I dont think I'll get any satisfacton from the dealer.

    Hi Pete,

    Mick in Victoria suggested I drop you a line and has said that you are pretty well on the ball with tech stuff and you beat me to it! Great to hear from you.

    The bike has 2000klms on it now and had the 1000 service not long ago. So the tank wouldnt have been removed I dont expect, but I will check the pipe youve suggested just in case. It's had the first service and as youve suggested, I'm considering doing a fresh oil change myself on the motor/box as well as the diff cos I don't put a lot of faith in the Yamaha dealer. I always wonder if they use good quality oil and the clunckiness seems to be when things are warmed up. To me it suggests the oil is thinning out too much. I'm not going to worry about the filter because of the difficulty with having to pull the pipes off to get to the filter housing..and Im pretty sure they did the filter at 1000.

    The carbie issue I might just be an adjustment issue and the dealer just fobbed me off last time I went to him a few days ago. Short of going to a specialist and having them do a proper adjustment and maybe even a dyno tune, I dont think I'll get any satisfacton from the dealer.

    Another yamaha dealer I spoke to in Parramatta (bike Biz) were very helpful and spent almost half an hour on the phone with me and the service manager seemed to think it's probably running lean. Just have to make the time to get the bike there cos it's out of my way and they are only open on weekdays.

    Anyway, I appreciate the advice...back to the drawing board!

    Keep in touch and thanks again.

    hey Frank, when you do your oil change try using a synthetic oil, it helps make gear box noises a bit quieter.

    Actually I was thinking just that. Alfie used the synthetic stuff in his 650 and I was a bit so so about him spending so much cos I used to use the Motul 3100 mineral stuff in my old 650. But Ive been thinking I will try the synthetic stuff and see if it makes any difference. I reckon the oil they put in at 1000klms just isn't any good and thins out too much at temperature. We'll see what happens in the next week when I get some new oil. Thanks again for the idea mate!

    Blah blah blah its all blah!!!!!
    Hey big brother and when I say brother now I mean brother flesh and blood!!!!

    Make sure you join the group I have created Aussie Yammie Cruiser Riders
    Go the Synthetic synthetic synthetic!!!!!

    Also BB which means Big Brother the popping (backfire) is unburnt fuel coming thru the pipes nothing major.
    With the oil filter BB think about doing a mob called the ORK?? Correct me wrong but you should find it in the top of the forum here. It's basically a relocation of the oil filter.

    Welcome to the family BB and make sure you say hi in the newbie section so everyone can see how ugly you are just kidding BB

    Luv Ya

    For 25 bucks and some time you can remove the ais . Barons has a good kit and if your going to change the filter Barons makes a good relocation kit well worth the money. The only thing with the kit is you have to relocate the rear brake res. It'll take you about 2 to 3 hours if your not mech inclined. Just take your time.
