valve adjustment 650 Sand Spider

Posts: 10

It sounds like tuktukusa is holding out on us 650 owners. Some photos and a step by step would help. What about all the other research to increase power? How do we get that info.? Have you done anywork towards a new-lower 4th gear? That would improve the 650 the most and a lot of people would be interested. If the manuals you listed are detailed and provide the info., that's fine, but it sounds like you've gone beyond that.

I have not been holding out on the 650 owners, I just found out they are being used in these buggys. Since I have worked closely with the engine maker for the last 3 years my knowledge of these are quite intense. I have had many additions and problems of the 650 removed for use and dependability in the USA version of the Tuk Tuk.
YES- you can super tune and I have also worked with the carb maker to have a special carb made for added extra power on the bottom end and top end for better performance and mpg.
As for my manuals, YES by far more detailed than any other manual offered. I do not offer simple repairs like how to change spark plugs, or oil change. But I do offer more internal repairs and set up with specific tourque specifications. That of which are not in the online manuals. Our manuals are copyrighted and therefor not offered as public domain. We do offer the manuals for sale just send me your request.
TTNA has spent countless $ in the tuk tuk project, not to mention the translations of different languages to make the manual.
Transmissions, well I use a different trans in the tuk tuk than the buggys use. Rather than look at the trans look at the differential, that is where the power to pull the hill will come from, but if your not getting fuel your tossing good to bad. The ket is to change over to our carb which is special made, you will see a great difference, then toy with gears.
OH - the manual covers expected performance ratings off the dyno and from looking at it, then studying where yours is you will know where to start about getting your buggy to run like a tuk tuk, yet pull those hills.
Our super tuned tuk tuk runs out to 73 mph, has pulling power equal to a 1/2 ton truck, and load capacity to match. Oh - yes can use off road too with the tire options we offer.
All I have to say is ask me what you need, if I cant answer my Thailand Engineer can.

Is there a website that shows the available upgrades, such as the carb? What about the manuals ordering info.? Please forgive me for semi-jacking the original thread. I could have sent a p.m. but I thought that others would be interested.

Dizze,
Since I have dedicated the website to the tuk tuk, and just realized the buggys are using the 650 engine I have not prepared additional website space for the additional items, however the site will be getting ecart soon. Until then we are doing it up old school way.
As I am not sure about actual post of the weblink in this reply, the link is available on my profile. I do not want to offend the site by posting improper response or reply. with information I can offer about these remarkable engines I do not want to offend the sysop by encroaching on his great site and be requested to leave or not participate with the site. I believe it is called respect.
The manuals I have are not like the public domain manuals, I have created much of the manual specific to the engine. As mentioned before the manual covers tourque curve expectations, and much more.
My super tune carb is made just for us, it is not available from anyone or anywhere else. It is the finest addition to power you can do.
BUT, I can be reached either by one of the two #s on the website, or email from the site.
Thanks

I have everything for the engine, the trans is different. However some parts will interchange.
Really the most important thing I have is the carb for making the buggy run like a top, the rest is right settings.
Example, Today I take one tuk tuk and work it out for better running. This is a new shipment tuk tuk not yet tuned for delivery. I take it out to see how it runs, it topped out at 49 mph. When I was finished I retested it from setting up the engine. It topped out at 63 mph. Plus and of course, now it takes off with a whillie if you want, tourque is great with buring off the tires. Now keep in mind that a tuk tuk weighs in at just over 1000 #, and is almost as large as a Ranger truck. So really performance parts ! The engines really do not need to much extra, just tuning.
The parts I have I just completed a parts book just for the Buggy Owners. How about question, What is your air intake system. Is it restrictive. Just a question to see how you are set up.
The parts book is part of the set with the service manuals I offer.
Let me know what else you need.

The only way to get fuel injection that I know of is to move up to the 850cc. They are fuel injection, with a hotter ignition.
Please supply me with detailed info about the trans, like model, and any numbers that are on the case. Maybe some photos too!
I can have my Thailand engineer check into parts and other things on it.
There is a 50 amp alt can get and is a R&R item so nothing to modify. I will get more on that.

Changing out the intake manifold and carburetor with an air/fuel sensor and throttle body injection would not be that difficult. Perhaps a higher pressure fuel pump would also be needed help atomize the fuel.

TeamJoynerUSA.com has the owner/part manual for the SandSpider 650 on line. There you can see the parts break down. I know we use the MT-2 version of the power train, but I will need to look for additional numbers on the casing.
