It sure is addictive -
if it's not I'd like to have it .
Yeah - but whose bike is that ??
That's why I want the 3rd guard .
I believe the one I uploaded earlier is the one of ZMA R

May be the oil specs have something to do with color - may be they add different color to different spec oil so that the ignorant guys at SVC can understand it easier.
Dont disrespect any bikers - 2 strokes have the best power to weight ratio - and the go is intoxicating . RX 100 / RX 135 /Fury 175 etc has its fan following . The 1st 2 are getting near classic status while the 3rd is almost extinct . It was the silent killer !!
They can be as funny as they like as long as they make good bikes

Both links you posted previously & now are same of Karizma Owners manual not the ZMR manual .. Can you please share link of ZMR owners manual


Yes those 2 strokes are really good RX100 , RX135 & Max100R from suzuki .

The tappet noise increases with heat and reduces with colder condition..which is why tappet adjustment(Valve clearance) should be done on a COLD engine and not a hot engine.Expansion of metal with heat leads to increasing GAP between them...Piston slap noise,gear noise etc., increase with heat,they don't decrease with heat, and you will always hear the engine to be noisy when hot, not when cold.

And Ashwin I guess you may now find a bit low performance than before adjusting the valve clearance,am I right?Actually the correct method is to set the piston at TDC of compression stroke,just after the inlet valve closes,and then adjustment is done.Tappets should always be adjusted when the engine is cold,reason explained by Psr sir!

I know sir, that you'r technically right, but when comming to the tappet clearance my experience proves the above statement wrong. I may be mistaken and if yes, please do correct me.
The expansion of metals causes gap betweem them, agreed. But dont they expand equally under similiar conditions. OK, if by chance they dont expand equally, but still the thingi below the tapet adjuster nut and the tapet adjuster nut expands in a conntradicting way right??? Then also the sound should decrease not increase.

And sir, here's one more theory which may or maynot be right, correct me if im wrong.

The tappets are adjusted at cold temp cause when tried to adjust at hot there wont be any clearance i.e if the gap was just a minor one. Else there would be an in correct gap, which would result in loss of performance.

Nope bro, I believe you'r refering to overtightening the adjuster nut because the engine was warm, which causes improper opening and closing of the valves, even we expected that issue to surface, but somehow it didnt. The performance of the bike was way better, thats how I was able to clock 125~130Kmph the day before handing over the bike to Harish bro.

there is no rule that the tappet clearence should be set only at tdc , tappets should be set when the rocker arms are free and not engaged by the cam lobes , it is advised to bring the piston to the tdc before setting the tappets as at tdc the cam doesnt engage any of the rocker arms and hence the tappets are free , allowing to set the clearence accurately , during the inlet and exhaust stroke the cam engages only one of the valves hence you can set the other tappet which is not engaged

Ashwin the reason for adjusting tappets at cold is that one can never adjust it when engine is hot, nobody wants burns on their hands . Just kidding the real reason is that if adjusted when hot after the engine gets cold the metals get contracted and thus the valves will get over tight and may lead to cracks on valve. Its better to have a loose valve than an over tightened one

If the tappets are loose slightly your top end will increase that's what is in your case . If its too tight top end will decrease

Went to svc yesterday,The replaced with New Ignition key,New T-Stem,Bearings,T-Bar,Handle Bar and New ZMA-R's front fender but used my old clamps to fit it ,so its not perfectly fixed,need to order the clamps and do it myself!

Bro edit and remove those broken/wrong links.

you need to read more buddy,

i dont know how you came to the conclusion that adjusting the tappets when hot causes the valves to contract and crack , adjusting the tappets too tightly does keep the valve open when they are supposed to be open this leads to loss of compression and so the bike wont start, or will lead to loss in power when hot, valves are closed by valve springs , not by tappets or cam , so dont worry , the valves wont crack any time soon

"If the tappets are loose slightly your top end will increase that's what is in your case . If its too tight top end will decrease"

the truth is on the contrary there will be slight increase in accleration when the tappets are set precisely or a little under the clearance specified ... i set the tappets on aswins bike myself using a feeler gauge and all the tools specified and i double checked it myself followed by ashwin and aneesh , so do not worry the tappet clearances are in spec

dont believe everything you read in the net , there is plenty of hogwash floating in there , i suggest you start reading some books if you are that intrested in it , automobile engg by kirpal singh Vol 1 and 2 are good starting points you can buy them from 2nd hand book dealers in palayam if you are good at bargaining you can get both the vols for about 250/-

Bro, you'r royally confused.
Take a look at the pics in the tappet DIY thread and you'll get a somewhat clear picture of how things work.

If the tapet adjuster's overtight nothing will happen, other than the bike refusing to start, due to closure of the respective valve, thats what happened to us first, and we were clueless, only when Sarin bro came along and explained the technical details we understood the reason behind it.

If a persons hands would've got burned when setting at hot then I guess KB100's now typing with his feet. Because during the DIY due to the TDC letting us down we had to do it manually and hence he had to do the setting even after we fired the engine a couple of rounds.
For an experienced person, the clearance is adjustable even when the engines abit hot. Though not recommended.

Thanks for correcting me. Knowledge upgraded .
