KTM LC4 frame perfomance

Two solution for the problem. In last commen that a number of possibles olutions, some more cheap than another.
Now I write my explanation, I decide for two, change a final relation, before 16-45 after 16-38, 7 teeth is much, but LC4 engine have only 5 gearbox ralation and have a more torque.

Solution: The engine work with 500 rpm less, good? 
I want to work more in this part, 38 teeth is as small possible for rear hub.Only solution is change 16 teeth front, 17 teeth but I need a mechanical modifications for this.

In Tony Foale book, show in one thumper engines, have a lot vibrations,  for example Norton in his old models , manufacture a rubber system for cut back vibrations engine,  in book explain, a cheap solution, connect  frame with head valve engine. When I design a new frame I have a all tube sframe, but in ktm have a engine, an electrical components, fexibles tubes, all and I need adapt to situation.


The exercise is:


Result, engine don’t transmite a lot of vibrations, It’s impossible to eliminate all vibrations, but good result for work. It’s very difficult work in this frame-engine because the hole is more small, but result is good.

Only more comment, with 38 theeth on rear hub, engine response is more slow, I think a lot solutions..........

KTM LC4 frame perfomance

Hi friends......

KTM LC4 is a old model of an austrian manufacturer. This engine has over 20 years, my model is a 2006 year old. The engine is very strong, it's true!!!!! no mechanical problems, no electric problems, it haven't an electrical components!!!!!!!!! jejeje.

But It have a one problem, as a one thumper, have a balancer shaft, it's necessary, that the vibrations with one cylinder is unbereable for road. Already this bike isn't for travel, but in seven years, my bike haven't a problem, only bateries and engine maintenance.

In seven years i travel to France, Italy and in this years to netherland, and I'm happy with it. I intend, to reduce engine vibration.

Problem: To 120-130 km/h and 5500 rpm the vibration is important, the vibration causes:

- Body tired (my ass !!!!!!!!!!).
- I don't drive with more speed, that increases vibration.
- Bolts screws, rivets, ...... broken and it's importan for safety
- In last travel (Assen) had a problem with electrical components (GPS) that with vibration had a bad function.


Causes:

- Reading in LC4 forum, this model have a big rear wheel drive, excesive for road good for off road. From manufacturer have a 15-45. My bike have a 16-42

- In LC4 USA forum I read the problem is in crankshaft, one thumper haven't a trade off.  When piston is on top dead centre, on lower point haven't a trade off. For example in ducati engine when one piston is on top dead centre another cilynder have on lower point. In one thumper, one balancer shaft offset another cilynder. I think a KTM LC4 have a mathematical mistake for balancer shaft. Is too small.

- With Tony Foale book, and his geometry frame discussion, explain if  valve cover is conected to frame reduce a vibration engine.

- KTM LC4 frame is oil tank of engine, for this the frame isn't tense, and vibration is big.

- LC4 engine have ony 5 relation gearbox.

Solutions:


- Change a chain relation. Easy

- Frame-engine connection. See a Tony Foale book. Is difficult but I don't remove a engine

- Crankshaft change. Uffff. Is difficult and expensive work

- Flywheel magneto change. Easy, expensive and HP engine loss. I don't like.
