I don't know what your scooter looks like but I am just wondering if you could do a simply modification. Of course head on air flow is always going to be stronger then a diverted air flow. However, if your head on flow is being restricted by the screen then maybe a diverted flow would actually be better and prevent stone damage. What I am thinking is to creat a box in front of the radiator using the screen as a front. But allow about an inch or so between the screen and the actual frount of the radiator. This would allow for air flow from both sides, top and bottom plus through the screen. I would think this would compensate for the screen blockage.

OK, now tell me that's how you already have it...LOL

On my Roketa 250 54B the fan cycled on/off no matter how hot the temp was outside or how fast I was riding. To be the fan should not be staying on all the time expecally at only 70 degrees. If you start the motor and let it sit and idle does it cycle on/off and control the emgine temp no matter how long you let it sit?

Botton line if you can't get it what's the difference?

The proper way to adjust the carb is to set the idle at the rated speed say 1800rpm when the engine is fully warmed. Now turn off the motor and turn in the HS screw to full colsed (CCW). Then reopen it to 2 full turns from the seat (CW). Now restart the motor and slowly continue to turn the HS screw 1/8 turn at a time until the motor reaches it's max speed. If needed during this process re-ajust the idle as needed (will likely require a few idle adjustments). When you reach the max speed while adjusting the HS screw you have the correct HS adjustment. Now readjust the idle to spec. and your good to go. And never mind those burns they will heal...LOL

Increased octane is to reduce pre-ignition only. It does not improve fuel eff or power. Higher compression motors require it because the higher the compression the higher the burn. This causes lower octane to ingite to quickly causing per-ignition (PING). In a car or truck you can hear the ping under load. This is a good sign to use a higher octane fuel. With a scooter or motorcycle you may not be able to hear the ping. Personally I always ran 87 octane in my Roketa 250 54B and it was very happy and I got 60 to 65mpg.

Hi Roy, So what size engine is your tiike running? I'm very surprised that you wouldn't get better fuel eff with FI. One of the main reasons most if not all cars have it now is to improve the fuel eff. And of course auto aduust for altitude and weather conditions. And while it will not provide a significant if any added top speed it should provide a smother stronger overall power band. But because it's a generic off the shelf system as you have found it does require a bit of tweeking.

The guy that did it on the 50cc had a bit of problems fitting the system in but I think that was becasuse of the small motor he was fitting it to. But in the end it sounded like he did get much better performance and fuel eff went up around 15%.

bobf....Your right these projects are not for everyone nor are they intended to be. Some people want to show a $ return for their efforts and there's certainly nothing wrong with that. But as indicated by others these things are more of a hobby then anything else. That is how I would dicribe it for you. Among other things I build and ride electric bicycles and and play with scooters/motorcycles for a hobby. I can tell you I pay a lot more money on my bicycles then I will ever invest in a scooter or cycle. Hell, I have over $1,600 invested just in battery packs.

Some of you may remember I had a 60mph spill a month ago and broke my right wrist and right leg and got to many bruises and road burns to count. The scooter (2008 Roketa 250 54B) was considered a total by Start Farm ($3200 in damages). They gave me a payoff of $2366 less my 250 deductable for $2116. Not bad considering I only paid $2300 3 years eailer.

I still have a soft brace on both my wrist and leg. But I say a deal on Ebay for a 2006 CF MOTO V5 motorcycle/scooter with only 618 miles on it. Problem is it didn't run.....DA, like that's gonna stop me. Bottom line it can spin and tries to start and sometimes does but can't stay running. Not a big deal I'll just strip it down and clean the fuel system real good and I'm betting it pops right over. Not in any hurry though. I still have another 3 weeks in my braces. It's hard to do anything with these things on and I really don't want to get grease all over them ether.

I've read a ton of great reviews on the bike but everyone says it badly under powered. The motor is the original Honda 244cc clone from CF Moto. The bike weighs in at 361 pounds so it's not much different then my Roketa 250 54B was. Anyway I maybe looking to do some inexpensive mods to up the power a little. But I really don't what to reduce the fuel eff. If possible. So if anyone has any thoughts please pass them on to me. Bob

PS... I only paid $550 for this bike

Some of you may remember my posting a few weeks ago saying I spilled my 2008 Roketa 250 54B. I thought I took the worse of it by braking my spraining my left wrist, breaking my right wrist and breaking my right knee and lets not forget a few good road rashes. I figured the bike was going to be maybe $100 to $200 worth of skin work and a partial paint job. Of course I figured I would take the insurance settlement and do the work myself.

Today I got a few surprises. State Farm called with a settlement offer. Now there's 2 interesting things to about this. 1) the fact that I opened the policy only 5 days before the wreck and haven't even paid the bill yet. And they agreed they will only charge me for 6 day (canceling the policy the day after the wreck). Why? Because the repair estimate came to $3150 so they totaled it. So they offered me $2,366 less my $250 deductible. I paid $2,300 for the scooter 8/08. Granted it only has 600 miles on it but still if not for my $250 deductible they would actually be paying me more then I paid for it. What a deal!! Plus they pay another $1,000 toward my medical bills which so far exceed $15,000 and I estimate will exceed $20,000 by the time it's done.

I am leaning 80% not to replace the scooter. At 64 I don't think I can afford anymore broken bones. And if not for my helmet and face mask I don't think I'd have a nose today. But we'll see what happens come spring time. But I am heavy into building electric bikes and I'm thinking to put the money that way. Yeah, I know I can fall off them too and have. LOL

PS...my bikes cost more then that scooter did when new.......
