Default planning a build..

Hi everyone, this is my first post! Great site I've learned a lot already looking through some other threads. Here's what I'm looking to do..

Build a motor bike for everyday use and hopefully some long distance coastal touring this summer. I have an old Trek 820 that was gifted to me I can use.

My questions are, will this be suitable frame? And

Since I will be using everyday and hopefully for extended long distance trips reliability is important for me. Second most is a quiet motor(I've read some threads about adding muffler and intake silencer). Without experience I am going to say power isn't a big deal for me. I'm very much fine cruising at 20-25mph. So from what I read Tanaka seems to be highly regarded for quality and reliability although it seems to come at a cost premium.

But before I get ahead of myself, feedback on whether the frame will work well. Next would be motor suggestions that are quiet and reliable.

Hi, I've got five bikes, 4 of them are 2 strokes and are a little loud, but the fifth one I just built I bought a 4 stroke from spooky tooth it's pretty quiet stock but I anded a flex gas pipe ran it to the back of the bike and added a lawnmower muffler on the end, it's nice and quiet and runs great no oil mixing,great on gas, and very smooth. what bike to use I like the Schwinn cruisers. either motor fits right in, and I think there very comfortable on long rides. good luck on your build can't wait to see your pics.

Will not be able to fit 2 or 4stroke in that frame. Sell the trek and buy a good cruiser from a bike shop not wal-mart and the sky will be the limit.

I just took measurements and came to that conclusion.

Also after more research it looks like a 4 stroke is going to be best motor for noise level and reliability.

I am a little confused though...

Everyone agrees the 4s operates at lower dB but I heard some people saying 2 stroke is more reliability and easier to fix/maintain. Then other people were saying the opposite.

I have built 13 2 strokes and one 4 stroke. The 4 stroke is not a stylish looking engine as the 2 stroke and is more expensive but the ride and next to no maintenance is priceless. I am on the list for the new titan in frame 4 stroke from dax. The 2 stroke requires maintenance nothing hard but if you just want to ride go with the 4 stroke. DO NOT MESS WITH THE gasbike net 4 stroke you get what you pay for. I can say the Grubee that bicycle-engines.com sells is good just do your home work ask lots of questions dumb ones too and you will be good. Lots of great help on this forum.
