bad idea. the timing on the RDD CDI is +4 degree over stock. The same timing on the stock CDI = too much advance = will melt the piston. Please make sure you're running the right timing at least during run in man. Its a critical phase for the engine.

If you wish to test, Revert to stock timing + stock CDI. You are running 17.5 pilots on a 5 speed carb which runs 12.5 pilots as stock. So no worries there. Am sending you a 260 mains soon. That ought to feed her well for the time being before we switch to a bigger carb

hey Atul that is what i said i moved back to stock CDI and stock timing. I already tried the 210 mains and she is becoming too rich to ride not sure how the 260 will be

**atul_astro** · 03-20-2010, 12:37 PM

oh thats great. Yes 210 mains with 5 speed carb will be too rich. Try a similar combination with the 4 spd carb. What plug are you using with the setup?

**jagadeesh.b** · 03-20-2010, 10:40 PM

I am using the mico w5bc plug. I will switch to 4spd carb once i get the jets from you? Are you sending the pilots as well?

**Nikhil Pereira** · 03-22-2010, 02:37 PM

Mr. Atul u seem well and alive here man. WHy arent you pickking your phone when im trying to call you. Sent you like so many texts. I dont understand the avoiding

**atul_astro** · 03-22-2010, 09:36 PM

Mains and pilots dispatched today evening. Let me know how they perform. Do follow the patient run in procedure for atleast 1000kms man. Once u complete that checking the top whack is worthwhile. Doing it now would neither give you an insane top speed and ur giving abnormal wear and tear to the liner and piston rings. Wait for the break in before you try anything again. Just a suggestion

@ Nikhil - Im pretty much alive and kicking man. I tend to avoid the phone coz I keep getting like 30-40 calls a day for general queries and advice and in the process I cant focus on either my bike projects nor my studies nor anything else. My family and friends cant even seem to get through to me, and I keep getting these calls right until 3am from 9am. It takes up too much time and an average fone call last about 20 mins. I am open to answering any queries via email/IM/PM. Its not directed at you or anyone in particular, just that I need to change my current way of working to be more efficient. No offense meant bro

Hope you understand my point of view

Cheers

Got the main jet from Atul. Tht thing must be atleast 250 plus. I have a 210 with me and it looks tiny infront of this one.

Finished 850kms till today.The bike is running smooth apart from a some piston slap. Atul already told me that he would like to keep more clearence.
The rear sprocket has been changed to 34 teeth. I did a small top speed run today since i felt tht the engine has freed up a bit she did 115kmph. backed off as i didnt want to push tooo hard.

Once the 1000kms run in is over i will switch back to RDD CDI and run 22 deg timing
Need to get 20,22 pilots badly.

@ Atul - WE checked the compression and it reads 200psi. My mech says that this is too high compression and that the bike will not have a good topend with high comp. He added an extra gasket today to reduce it. Is this true and what is the recommended compression. I know stock comp is around 135-140PSI.

**atul_astro** · 03-31-2010, 01:26 AM

thanks for the prompt feedback jagadeesh

good to know the bike is smooth now. 16/34 is a good combination to try out for sprocketing. I'd suggest you move to 15T front and check what kinda revs she is hitting in 4th and 5th gear.

Try and shift to a bigger carb [28mm or above] preferably a Keihin pwk or a TM. Also check your stock fuel tap for better flow. If we're able to source you a TM28 or a TM32 that'll be good. Do finish your 1200 kms and we'll switch to a neat pipe

WE checked the compression and it reads 200psi. My mech says that this is too high compression and that the bike will not have a good topend with high comp.

good to know the rings are sealing well and she's putting out some mighty compression. I'd recommend running between 18-20deg BTDC and running the best fuel you can. Try a run with the 5 speed head and tell me how she's behaving. That way i'll be able to recommend something

Good to know the update man. A few more kms and we'll put a pipe on that thing. Then you should be good to go and the setup will unleash its true potential

In the meantime try getting a 25 pilots or a 27.5 pilots [RD or bullet] That will ensure she runs cooler at idle

**jagadeesh.b** · 03-31-2010, 01:33 AM

i tried the 25 pilots on the 5spd carb and she is very rich.

**jagadeesh.b** · 03-31-2010, 01:34 AM

will switch to 4spd carb, the mainjet u sent and 25 pilots this weekend.
Also will look for 15 tooth front sprocket

**jagadeesh.b** · 03-31-2010, 02:56 AM

@all - Another quick question. How much speedo error do you see when you switch to a 17" front?

I have touched 120kmph with the RDD CDI, UNI and the 100/90 kit. I tried running ti with another modern bike beside me and that bike was reading 110kmph.
So by default there is around 10% speedo error on all analouge meters and now if you switch to 17" wheel in front you get another 10%?
so total 20% speedo error??????

**jd666** · 03-31-2010, 03:00 AM

^^ yup pretty much.. 10% error for the wheel diameter, and 10-15 % for the speedo.

Hey buddy...nice to know u have a pocket rocket under u. What is ur timing for 0-60 and 0 - 100. Check my Yam's video.

YouTube - 0-60 in 3.5 Secs and 0 - 100 in 10 Secs..not Bad !!!
