Ride Report with M45 3.25x18

After running my ZMA on M45 4.00x18 for few years, had been lucky to get hold of 3.25x18. Initially there were lot of difference, i.e height reduced, there was a change in handling, due to reduction in height, my sitting posture changed too. I had taken the bike to Avelanche, Nilgiris this weekend and here's my observation:-
1. Took time for me to adjust say, first 100kms was a challenge and after I could get adapted.
2. The turns felt lot quicker, but the grip of M45 kept my balance stable during the corners.
3. Somehow, I felt not much difference in acceleration.
4. Luckily the roads all the way and return was excellent that I had little worries about my tubed tyre.


Another observation:-

It was nice to ride with [MENTION=20165]phanikar[/MENTION] who joined from Bangalore. While checking my front brake and compared with each other, we tend to think that my mastercylinder is either need attention or replacement. I did not enjoy my speeds this time during ontowards journey, but felt lot more peppy in the return. Strange.
The usual symptoms of carb slide stuck did not occure even once that, I felt wierd (lol).
Osram Nightbreaker Plus's low beam is awesome compared to high beam where the beam kind of concentrated. Still lot of improvement. The reflector is shaky and PSR Sir suspected some loose mount point or screw came out.

Re: Karizma/Karizma R

@sriram Good ,to know that even the 3.25 18 did not give you any anxious moments, and to know that the throttle slide problem did not repeat .Regarding the master cylinder suspicion, a change of oil and cleaning the cylinder is likely to improve brake response...get it sorted out before next trip..

Re: Karizma/Karizma R

Since I noticed there is a lot change in handling while i took a spin before the trip, had been very cautious that I could not go beyond 80. Only after 100 odd kms, slowly my confidence went up. Yes Sir, will have to do some maintenance to the MasterCylinder.

My bonding with the bike only increases everytime I take it out for a road trip. The confidence, the riding comfort, the stability, the reliability!

Re: Karizma/Karizma R

That's the spark about ZMA. The more you ride it, the more you will explore about the bike. Its capable of doing stuff we never imagine when we buy this bike .
I have done 72k odd kms...still falling in love with my ZMA each day, in a new way!!!

Re: Karizma/Karizma R

The Pulsar 180/200 Valve door nut has same thread, but with a larger nut head which will help in proper tightening and easy to loosen it ...here is a picture of it..

Re: Karizma/Karizma R

Few important things that I learnt in my recent experiences with Karizma engine.

1. Do not repair the crank. Stock one goes for at least 1 to 1.5 lac. Don't bother by the conrod side play, unless you have rod-knock symptoms.
2. Always replace the camshaft and rocker arms as a pair. Do not replace only the camshaft. You can replace only the rocker arms but not just camshaft.
3. Replace camchain and tensioner as a unit, unless the tensioner fails its function.

Re: Karizma/Karizma R

I have used it for that purpose..when the original one got damaged. My mech took one from a pulsar and fit it. It is more easily available than OE part.

Re: Karizma/Karizma R

Thanks for confirmation....so it seems to be a better option and does suit ZMA/ZMR.

Re: Karizma/Karizma R

My tensioner has gone kaput. Do I have to change the camchain as well?
My clutch plate is also worn out. Do I have to ask the svc guys to change the pressure plates along with the clutch plates or they change it as default?
Can I get the rubber behind the Headlight as a spare from SVC, here in Bangalore one svc guy said we will only get it with a new doom

My bike is behaving weird when I ride it 120+ kmph for 2-3 kms. It just looses grunt and it feels like the engine is going to shut off. If I slow down upto 35-40kmph, I can accelerate again and catch up speed. But the samething happens again if I keep on riding it on higher speeds for a min or two. Last time I faced this issue when I was riding to Goa last year. It was showing such symptoms for 100-150kms and then it finally stalled. I had to put it in a lorry and take it to Hubli HH svc. Some issues with electrical connections was rectified as current was not flowing properly. There was no issues with any of the coil or CDI. The mechanic fixed it in an hour and I did not face any issue for next 1000 kms in that ride. I did cross 9.1k rpm in 5th gear as well.
But I am facing similar issues again. How ever I did ride for 120-130kms last sunday in around 90-100kmph speed and I did not face any issues. I am not sure if cluth place can be the culprit.

I am going to pay a visit to SVC to change my camtensioner and clutch plate. but I am sure the svc guys can not catch the other issues. Its really unfortunate that they fail to identify or fix any issues till you tell them where it is or till your bike stalls completely because of it.

Re: Karizma/Karizma R

Forgive me for this stupid question, but if your bike has worn out clutch plates, how's it hitting top speed figure s?

Woohooo, tapatalk works on my phone!

Re: Karizma/Karizma R

I never said it hits top speed figures now. I crossed 9100rpm on 5th gear before 7-8 months. It goes little more than 120 kmph now. I am not very sure that with a worn out clutch plate your top speed will be affected a lot.

Any help will be hugely appreciated

Re: Karizma/Karizma R

First, if clutch plates worn out, your bike won't be able to accelerate to 120+ speeds. You need to understand Karizma goes quickly to 100 kmph and then slows down a bit to reach 120 kmph and then it takes eternal time to reach 140 kmph (under favorable conditions). I suspect your bike shut off above 120+ speeds because you were riding above 8.5k RPM, where rev limiter kicked in killing the engine, which is quite normal. Your bike would have started if you had waited for 15-30 minutes.

Your bike doesn't have any issues with clutch plates, else you wouldn't reach 120+ kmph. I feel everything is normal. I suggest you to keep riding around 110 kmph and not above 120+ kmph for the safety of both you and your bike.

Regarding the tensioner, is it making any noises? If not, I guess nothing is at fault.

Re: Karizma/Karizma R

Yes, The Tensioner is making noise and I do recognize it. It need to be changed.

I do ride at sane speeds, but my concern is the bike shouldn't shut off at higher speeds as well.
Apologies, I forgot to mention all the modifications done in my ZMA.
RC Big bore (40k kms)
RC Free Flow exhaust (10k kms)
RC Racing CDI (20k kms)
Semiflat 33mm Carb (20k kms)
Freeflow Universal Air Filter (10k kms)
RC Racing Camshaft (1k kms)

Neither I am kidding nor any of the facts mentioned by me are incorrect. I am sure I don't have the rev limiter as I have touched 10k rpm as well.
@PSR Sir, You and me share the same date of Birth (not year though ). Please provide your expert inputs!!!

Re: Karizma/Karizma R

Now, I will leave this to PSR sir's expertise.

Regarding tensioner noise, I suggest you replace both camchain and tensioner.

Hey Sorry Ravi...My intention was not to offend you. We all are here to help each other, are not we part of the same biking brotherhood
