Venom sound- normal?
« on: June 14, 2012, 07:05:42 AM »
Hi guys
Had my bike for a month, and I've noticed my bike makes a sound I haven't heard before.

When I accelerate or at neutral and rev - I hear a "flapping" sound. It sounds like it's coming from the bottom of the engine. Can anyone verify their venox has the same noise?

I'll be heading to the mechanic in a week, but at the moment I'm concerned :O

Thanks in advance

Don't wait till next week J.B. Get the bike back to the dealer ol mate & get it fixed ... your under warranty!!! And don't forget to get your copy of the workshop report so you've got come back on the issue. Just my opinion ... regards, Hairy Bob.

Ahh true, I'll head to the dealership mechanics first thing in the morning. Really hope it's nothing   :'(

I went to the mechanics yesterday and from what they can tell without proper examination said, 'doesn't sound like anything, but if you are concerned book an appointment for a day's inspection'.

I'm due for a first service soon, and hopefully when they inspect the noise it turns out to be nothing.

Although, I've read some forums about 'flapping' or 'clicking' sounds regarding the engine - and it relates to a clutch belt being worn/damaged. BUT I've been reading the Venox250 Service manual and I don't see any 'clutch belt' - Is it named/technical named something else other than clutch belt?

My bike's first service @ 1000km

Bloody cost $264 ;D   $170 just for labour... and they only had the bike for 2 hours

Anyway, apparently the 'ticking/flapping' noise was because of a loose 'clutch plate', they tightened it and it's not as loud.

She runs better I think, from the ride home ;D and now that she's done 1000+km, I can ride the bike faster than 60kmp/h haha. Can't wait for a highway ride.

Been reading a little about the Venox, and because it doesn't have a tacho I was a little nervous about when to change the gear.
I USED to change the gears as follows:
1st = 0 - 15 kmp/h
2nd = 15 - 30 kmp/h
3rd = 30 - 50 kmp/h
4th = 50+ kmp/h

I never realised that bikes could take the high revs and so from reading a few reviews;

1st = 0 - 35 kmp/h
2nd = 35 - 60+ kmp/h
3rd = 60 + kmp/h

And apparently ( I haven't tried yet ) 2nd gear can go up to about 80-85 kmp/h before shifting into third ;D

during engine break in you should keep the speed limits yes! but do not overload the engine running on lower gears. 1st should be used to 25ish at least. and gear to gear changes should be used with the engine in working rpm. you should be able to feel it, when the engine is running at the correct rpm, smooth acceleration with little to no vibration. running on low rpm and heavy load on a new engine does not give the parts a proper mash, and is a high risk for premature wear, and the worst is ring sticking/tracking which will never be fixed without changing parts.
dont remember when i shift but 30km on 1st and 50km on 2nd with easy 60km on 3rd. under 1000km you should not be in 4th that much yet... bust since you are now try to use the engine more on the power band. my is now in the 6000km range. and some times i accelerate hard, but still never hit the limiter yet, you will feel the engine rpm and know when to change soon enough.
do not rev the engine in neutral, it is very bad, the parts were designed to take load at high revs and without it will cause wear.

yeh, I did ride below 60 kmp/h until my first major service, and I was thinking for the first 700km I didn't rev the bike high enough to 'wear the engine' in, but I guess it should be okay. I've been riding the bike using high revs (1st gear 1-35 or 40kmp/h) and then (2nd gear 35-60+ kmp/h). I haven't gone past 80kmp/h as I'm restricted as a "learner" to 80kmp/h

I don't often accelerate hard, and I usually ride normally.. I do rev the bike sometimes in neutral (probably up to 3k-4k rpm not much) guess I need to stop that habit ;D 

I'm planning to bring the bike in for a safety inspection at 2000km because I've only been changing the gears 'as it should have been' and as you mentioned, the bike was't getting 'worn in' whilst I was changing the gears too early compared to now.

Wasn't too happy with the mechanics at the dealer charging me $170 for 2 hours of labour (which is counted as 'a whole day's work'), so I'll be going to a local bike mechanic for this quick safety inspection/service for a fraction of the cost.

Thanks for the advice
