Re: CBZ xtreme / Hunk

I checked that too.. Float valve would fit only in one way into the groove. May be i will give one more try later to confirm.

Re: CBZ xtreme / Hunk

Krishna, don't leave this man. He is perfect along with psr sir to solve the "tilt me, I shut off" and the lean running problem. On further contemplation, I think the float height is wrongly set in your bike making the level of petrol less than optimum in the bowl.

Re: CBZ xtreme / Hunk

What a feat to achieve! [MENTION=28527]sibun[/MENTION] how do we celebrate this? Can there be a better time than this to write the third part of CBZ Xtreme's long term review?
All the best

Re: CBZ xtreme / Hunk

By the way my extreme has crossed 99k Kms.

Now will touch 1 Lacs next week

Re: CBZ xtreme / Hunk

CB unicorn alloy has gearing of 15/43
Yours has 14/43.

So in effect you are dropping 500 rpm in 5th gear.

That is causing engine to lug and loosing torque.

So you are loosing put on fuel efficiency.

Re: CBZ xtreme / Hunk

I hope the bulb in question is DC powered, else its just a matter of time before it blows.

Re: CBZ xtreme / Hunk

It is plug and play only.

Re: CBZ xtreme / Hunk

Replaced chain kit with CB Unicorn alloy wheels. Average went down to 30 from 42 in city..

Re: CBZ xtreme / Hunk

how? can you made a video about it.

Re: CBZ xtreme / Hunk

Changed number plate bulb to white LED.

Re: CBZ xtreme / Hunk

1)My Hero Xtreme vibrate after speed of 60 shown to service centre but they says it's normal
2) at ideal my rpm needle flacuate like 300 rpm flacuation is there but at higher rpm it's not
3)2-3 second delay of acceleration while acceleration
4) 5 k rpm 5 th gear it goes to 62 speed
5)I am using 10w30 Hero engine oil.
6)my odo I 57k and don't know about past service and some tik tik noise from engine head I talked to SVC guys but they told me this is normal and as they said they adjusted tappets but no change in sound is seen
7) I want to measure compression of my bike can svc guys do that compression test
Other vise no missfiring nthing is happening it goes top speed of 109 km without any issue acept vibration
Pls sujjest me for the issues happing to me.
8)My spark plug after 160 km its one side cockalaty coloured and other side it still white in colour.
9) I go for cleaning of head as suggested by user when my mechanic open air filter box some 6-8 ml oil is found where this oil comes from what is the issue ? Is there any issue from air injection system what is the problem behind this what is the function of part that stays near the air filter and this part's one line connect in between engine and carburettor what it does pls guide me for the same

Re: CBZ xtreme / Hunk

Get it cleaned from a trusted local mechanic. Castrol Activ 4T 20W-50 (MINERAL OIL) gives good performance. Change it every 2500 km, don't add top-up unlike the Hero 10W40/50SJ ones. That will give you a better performance atleast. I've friends who use 20W-50 in their Hunks/Achievers which uses the same engine as Xtreme. I've personally used 20W-50 from Castrol in my brother's Unicorn. It performs really well. The shifts are really smooth and you don't feel any engine noise when down-shifting. The smooth spot hits at about 4500-5000rpm for shifting and you can barely hear the level shift sound. If your oil color doesn't change easily and remains good, it means that your engine is healthy. It might just need some carb tuning for mixture (spark plug issue mentioned earlier) and while head cleaning isn't done unless you've issues even after carb's adjusted, get it checked with a nice local mechanic first. TBH, Hero SVC isn't what it was supposedly in the old days. Hopefully this helps you to diagnose the problem somewhat.

Re: CBZ xtreme / Hunk

Rpm flacuation at ideal is 300 needle flacuate between 1200-1500 rpm constantly and tappat adjustment not done
Is 20w 50 is good for me or not as no bore kit change no oil seal is change after 300 km oil colour is as stay as new
For head cleaning where to go SVC or local mechanic

Re: CBZ xtreme / Hunk

Since you're already at 57K on ODO and out of warranty, I would recommend switching a 20W50 oil like Castrol activ. Spark plug issues? I think you need to get your carburettor mixture checked for any abnormalities. 160kms is way to less for such an issue to happen. AFAIK the tappet noise from noise often accompanies with carbon deposits on plug at times. Does that happen for you?

About the part where you talked about idle RPM, did you mean 3000 instead of 300? No bike goes to 3000RPM on idle under normal adjustments. Hero Xtreme tends to vibrate on high speeds and it's a known thing. There's no solution to it really but if you're facing any discomfort, I would suggest checking the above and getting your head cleaned.
