I've taken my chetak 2 up on the steepest most ridiculous hills San Francisco had to offer, it can be done, just don't try to shift, it's not worth it.

By the way, Ramona Avenue, which is the 2nd steepest road in San Diego, has a slope of 28.3%. It looks like there are only three roads in San Francisco that are steeper. But this one is 1,900 feet long!

So, we're you in first or second gear? What happens if you have to stop? Lastly, have you had the TRICS mod done?

Well if you are 2 up, or really heavy, on a really steep hill you should stay in first and keep it reved up pretty high, you really don't want to miss a shift or stall on a really steep hill! If for some reason you do have to stop be sure to use the back break, the front will not hold you when all your weight is on the back wheel and down hill, my mom dropped her scoot by trying to stop during a rally on a very steep hill when someone stalled in front of her. If you only use the front break the tire will just start sliding backwards. Be careful getting started again, it's really easy to pop a big wheelie. I missed a shift from 2nd to 3rd once on a big hill and tried to go back to 2nd, found 1st and got vertical for a second, scared the guy behind me and scraped up my license plate holder but I recovered ok. I have had the trics mod on and off, I'm inconclusive about any real gains or losses, although I do seem to get worse milage with it disabled. I think the extra rpm it gives you is useless without additional mods because there isn't much power available at that high RPM.

Wow, what an awesome reply! Thanks for taking the time to post, munkeyjump. It sounds like you've got a cool mom as well. Sorry for the thread drift y'all.

Here are the pics I originally posted with this thread. For some reason the post I made went away...anyway...



I have personally come to the conclusion, that this mod does nothing noticable for performance. In theory it probably works, and there may be a small increase in power, but my scientific seat of the pants data doesnt give me conclusive evidence of a performance gain Wink

Post Easiest or hardest TRICS Mod? Reply with quote
I decided to do the mod at the throttle sensor as tmille53 did and synchro describes in his post and pictured at the link he gives here: http://webpages.charter.net/sydney/images/Bajaj-Chetak/AltTRICSMod.pdf

When I took the top off the handlebars I got a surprise, the mod had already been done, by accident. There is a black sleeve with a tab on it that rotates with the throttle and activates the optical TRICS sensor. A wire quick release cotter pin holds the black sleeve to the throttle assembly, cleary seen in the pictures in the above link. That pin was not connected but was broken and laying in there loose. Without the cotter pin the black sleeve doesn't rotate and the sensor does not activate. So, just pull the cotter pin and your done (after reassembling everything that is). Put the cotter pin back in if you want your TRICS back. tmille53 says he completely removed the black sleeve, but you can just leave it in place. Without the cotter pin it won't turn to activate the sensor.

Somewhere else in this post somebody talked about taping over the sensor in the handlebar. I don't understand how that could work. Taping over the optical sensor means it would always be blocked, just like having the throttle sleeve tab covering it at half throttle and more. The timing would always be retarded, which is what we don't want.

The hardest part to the throttle location mod is disconnecting and reconnecting the speedometer cable when you take the cover off the top of the handlebars, and that isn't particularly difficult. You also have to remove the mirrors and the four screws that hold the instrument panel halves together, as well as the headlight ring. In hindsight it is probably much less labor intensive to go to the CDI unit under the left cowl and do the mod there.

I'll never know if this mod helps, since it had already been done, albeit by accident. My bike runs pretty darn good since it's now got 350 miles on it, and I've done the first oil change and made a slight valve adjustment.

Post look ma no trics Reply with quote
the best thing i did was to install a racing cdi unit and it does away with the trics system completly and gives a more progressive timing curve with more advance a real noticable increase in throttle response and top end power. for my next step i am in the process of getting a racing cdi unit that is adjustable as far as timing curve and advance this should really set my engine in a fit.

Hi roy!, would you please indicate the part# and where to get it from, that sounds like a great alternative performance wise...

thanks

I am not really insterested in the real hot cdi but a mild cdi unit much better than the stock one will be cool to have,
thanks

what would be really sweet would be to adapt a Vespatronic or Parmakit ignition. Then you could get adjustable curves and what not Cool

I was just doing some reading on the TRICS mod and ran across this nonsense...

I have one question... "what kind of messed Up deal is this?"

" I felt like I was in grade school when I read his post...

I see he hasn't posted again on this thread since April 07...

I am sure your post was meant light-heartedly but Roy has serious health issues and sometimes cannot leave his bed for weeks at a time.

Post heads up Reply with quote
Rob, thanks for the heads up... I posted this after I first read his post...
later last night I went on to read more on another thread... and a few
comments posted from others who too were aghast by his posts...

I also noted that in his posts had lightened up after... Questionmark
hit the nail and the head... and even though RTB got a little pissed he did
come around and to his credit began to play nice... a welcome event.

This is a great group & I am enjoying it a lot.
Im glad I was able to find other posts from RTB and others...
The guy really seems to know his stuff and is a great asset to all of his
new & old friends alike here in this forum...

I did the TRICS delete too. I used basically the same method as the Argo site but without cutting anything. First I made a jumper using the smallest female crimp on's on could find.



I then released the male spades from the main connector and slide them out. On the now unused wires a small piece of shrink tubing around one and then a larger piece to encase both. Shrink wrapped the Black/red wire to protect the connection completely and then slid it back on the original post. Then reinstalled the remaining connectors and the CDI.



The leftover green male block went into the "Chetak" box in the garage should I want to reverse it everything is still intact without any cuts and minor assembly. I was only able to take it for a few spins around the hood so my butt-o-meter really didn't get a good reading tonight. It did seem to have a little more pep. I did not detect any odd noises. It does cut out a little when I really wind out the gears at WOT. In the stretches I only have enough room for short bursts of 55 mph so too soon to say for sure what the real effect is. Wink

I just did the trics mod and it honestly feels like I'm getting better acceleration in first and second gears.

Just did the Trics mod on a Legend with a POC. It did not help with my backfiring issue as some else mentioned it did on a Chetak with an HRA pipe. I'm wondering why it would of helped them as the backfiring only happens with the throttle closed? Anyway, I didn't notice any difference. My sensor is much different then the Chetak but can be easily accessed by removing only the front headlight plastic housing. I just removed the sensor and relocated it with one of the supplied screws so it wasn't effected by the Throttle tube. Easy enough to do on the Legend.

There can be lots of difference between any two scoots, carb tuning, air intake, compression
