I have installed a Raw motor on a mountain bike. My carb will not fit under the frame. Can I install a small angle adapter to place the carb at an angle outside the frame? Will the gas get to the motor? Thanks Dale

Yup. Several people have done that, often using copper plumbing fittings. One thing to keep in mind is that on a 2 stroke, intake length can have an effect on the power band. Theoretically a longer intake run will give more low end torque, and less high revs.

Thanks for the quick reply. Heading to Lowe's plumbing section this after noon. Thanks Dale

There is zero room for a carb on my Mongoose Paver. I have an adapter to a larger size for my CNS carb then a clear plastic tube that's fuel proof then into a massivly ported CNS carb intake from Pirate Cycles. The tube acts as a shock absorber for the carb. It can take a hard slam from potholes without transfering the shock to the carb....in theory
Longer intake passages, up to a point, can add torque. There's a small block Chevy intake for racing called a "Torque Link". It has much longer than stock(or other raceing manifolds for that matter)port runner designed to help stock-based motor to develope more torque to help them out of the corners.
A longer intake port is a tuners way to make max power.:helmet:

wrong on the long intake runners making more torque on a small block chevy. Go look closely at some of the street and race manifolds. Notice that the manifolds made for idle - 5500 rpms have short, curved intake runners and a dual plane plenum design. These intakes make low end torque.
Intakes made for 5000 rpms - 8500 rpm's (or more) have straight, long runners with an open plenum design. These intakes make more power at high rpms and are pretty much useless until you get into the suggested rpm range where the intake flows best.
If you run an intake manifold on a small block chevy that has long, straight runners on the street, the car will be a pain in the neck to drive in traffic because the low end torque needed to drive normally won't be there. On a street engine you want to make most of your power on the low-mid range where the engine will actually be in that rpm range. it's doubtful that most street engines will see 6000 - 8500 rpms constantly.
On a drag race motor you want to make most of your power midrange-top end. you want to kill off some of the low end torque so you don't burn the tires off the line. You can help the engine get into the rpm range faster with a stall speed torque converter.

a 2 stroke engine is a different animal and it may work opposite for them...i'm not sure on that.

Whatever...I'm sorry for being so intelligent.

...have you ever even seen a McFarland Torque Link Manifold? Completely different design, made for making more torque to help large small block race cars pull out of the corners harder.
Don't quote to me on what the various forums have to say about the Torque Link, the vast majority are drag racers and have a different need that an oval track car. That's why there's more than one manifold made and even then many times the selection of the manifold is made by the scientific method of brand loyalty and not what is the actual best performer.

yes i have seen a Mcfarland torque link and guess what...they are for MIDRANGE torque, not low end torque.
If you google that intake you will find that there are a lot of statements saying that these intakes are made for high rpm oval track engines.
the intake is essentially like a single 4 barrel tunnel ram intake, which has long, straight runners....good for 3500- 8500 rpms.
They are not good for low end torque...I'm telling you, if you want low end torque, short, curved intake runners is the answer (on a small block chevy anyway).
I'm not saying that this is a bad intake manifold and they actually do make a lot of power...but it's midrange power.
