Well in that case, I feel I need to get the clutch plates changed. I did not do that when the engine was bored as the mech said they were still in good condition. I may need to do that sometime soon ... or wait till the service date when the carb will be cleaned out too.

Also can the loss of compression be related to seal leakage, like valves etc?

Yes ,compression,carb tune,clutch plates all act on how well the bike responds.
If valve seals start leaking oil the carbon gets collected on the valve seats and compression will be lost.But your bike isn't drinking oil.

================================================== ==

Well now that I have the bigger picture, my agenda for the next servicing visit is set. Ge the compression test done, Get the clutch plates changed, The oil filter will be changed, Carb and Jets cleaned & adjusted ... along with the regular service stuff.

Don't go around changing clutch plates,unless they are worn out.Get the carb checked and tuned properly.

try this on an rx and you shall know it.

RX 100 wakes up at part throttle position..or above 4K RPM.KB 100 wakes up at 5 K RPM. Every engine has it's power and torque curve setup differently.An engine meant for commuting is set up with good low end torque,and maximum mileage .A performance engine is setup differently..... Suzuki GS150 and Yamaha R15...Both are 150 cc,but are worlds apart...just my thought.

Yeah absolutely! It depends on what you like.Fiero is a top end biased machine.F2 was made more traffic situation friendly ,but still ,they are not as low-end biased as the latest bikes.The RTR and R15 are similar in character,despite being the total opposite in bore and stroke config.That brings the cam and other tuning into picture,which has made them similar.

Two strokes make power once in every 2 stroke ,were as it's once in every 4 strokes for a four stroke bike.Which is why 2 strokers have a linear torque curve were as fours strokes are peaky and make power at higher revs.

Hi every one ,i am the proud owner of classic fiero,but my fiero is not in good condition.

can anyone suggest me a good mechanic in pune for Fiero

1.Speedo meter is not working
2.Tic-2 sound is coming from the engine(mechanic told me that camshaft and rocker need to be replaced)
3.Rear drum needs to b changed.
4.paint job is required.

its not like just ride at a particular rpm and then wack it up all open.

the idea is getting a rhythm first and then wacking the throttle hard, not all the way to full.
if you guys are familiar with wheelies, you'll realize that there's no idea as after so and so rpm, wack the throttle and stuff like that.
you need to attain a certain speed, make sure that the throttle is completely gelled in well and then wack it up hard and move 2-3 inches behind, what actually happens is that the front wheel lifts off...

now this very same thing to be done at a higher rpm and a higher gear is what gixxer is telling you to do...
try a lower gear (2nd for example), keep it at cruising speed meant for that particular gear, rise the throttle to a mm SLOWLY first when the bike tries to revv due to that mm of increment, wack it up, you'll realize a jerk, do this once or twice and you'll get that RHYTHM, now just put it on third gear and try, similarly put it on 4th gear and try.

its like counter steering, you'll have to experience it to know how it works, go ahead and give it a try..

the compression of the fiero will be 150 psi, and that thumb over the knob wont help, your compression gauge doesn't give you the figure of 150 all of a sudden, it rises to 100 in first kick, rises to 125 or so in the second kick and then reaches 150 in the third or the forth kick.

how old is your fiero ??
how many kms has it run ??
speedo issue can be solved in a cheap and easy way, tick tock sound can also be the tappets (unlikely though), or your timing chain, any more unusual noise like metal grinding or something like that ??

tintin here (who started this thread) is from pune i guess !!

Ya Nanobhai i m from pune!!

dude u have to check the speedometer. if the fault is in the meter itself, so i guess you will have to replace the whole unit, or the problem may be with the speedo cable...

regarding the tic tic sound, i guess its from the tappets..

Rear drums or the liner?? drums r a bit costly. u will have have to consult with a TVS authorised service center.
where do you stay in Pune??

and the paint job will have to be done from a paint shop that does Car/bike painting..
